上一篇下一篇目前有bug，特别改了排序后就会出现问题，土方法计算的代码如下：

{php:$list = phpok('_arclist','pid=2&psize=500&cateid='.$cate_rs.id)}
              {loop from=$list.rslist key=$key value=$value id=list_id}
                {if $rs.id == $value.id}
                <!-- php -->
                 $num = $list_id[num]+1;
                 $num2 = $list_id[num]-1; 
                <!-- /php -->
                {/if}
              {/loop}


              {loop from=$list.rslist key=$key value=$value id=list_id}
              {if $num == $list_id.num}
                <!-- php -->
                 $xia = $value[id];
                <!-- /php -->
                {/if}
              {if $num2 == $list_id.num}
                <!-- php -->
                 $shang = $value[id];
                <!-- /php -->
                {/if}
              {/loop}



{php:$arc = phpok('_arc','id='.$xia)}
下一篇：{if $xia}<a href="{$arc.url}">{$arc.title}</a>{else}没有了{/if}

{php:$arc = phpok('_arc','id='.$shang)}
上一篇：{if $shang}<a href="{$arc.url}">{$arc.title}</a>{else}没有了{/if}
